The Ventana Family of Single Board Computers from Gateworks offers a multitude of video and audio interfaces to meet the demands of new multimedia embedded systems. The primary method of accessing these interfaces is through software by the name of GStreamer. GStreamer is an open-source library that makes the handling of multimedia data more simple usingpipelines of elements that operate on multimedia data buffers. GStreamer can be used directly on the command line of a Ventana Single Board computer for quick prototyping and development with the gst-launch test application. For example, to play a video file stored on a USB …

Read MoreGateworks creates Single Board Computers (SBCs) that have very unique and powerful features that are not found in other SBCs. One of these features is the Gateworks System Controller (GSC). The GSC provides system health parameters to the user along with additional specialized peripheral functions. The GSC is battery backed allowing monitoring when the main board power is removed. Some features include: Tamper detection Encryption Key Support System Voltages Board Temperature Fan Controller Real time clock A programmable user push button An advanced power management with a programmable board shutdown and wakeup General purpose digital I/O To read more about …

Read MoreCollect data, video, and audio anywhere with a powerful, low-power miniature Single Board Computer (SBC) made by Gateworks. This white paper discusses the use of a miniature, powerful, low-power single board computer (SBC) with multiple networking interfaces to collect data from a variety of sensors (such as temperature and voltage) and video images from a camera. Specific topics discussed include power management, network connectivity, and sensor interfacing. An example application is provided using batteries for power and a camera to take periodic snapshots which are uploaded using the FTP protocol to a website for monitoring. Gateworks has published a variety …

Read MoreUnder certain high load conditions in OpenWrt, using dual-core Laguna products, Ethernet ping latencies could grow to an unacceptable value. After investigation, Gateworks found an SMP race condition as the cause in the CNS3xxx Ethernet driver in Gateworks’ 13-06 and trunk OpenWrt BSPs. Note that the 12-10 OpenWrt BSP is not affected. Gateworks has resolved the issue with upstream patches to OpenWrt: http://dev.gateworks.com/laguna/images/ These fixes have been committed in both the Gateworks 13-06 branch and trunk. Gateworks recommends all customers using dual-core Laguna products update their firmware.
Read MoreFrom time to time we get questions about floating point math on ARMCPU’s. As it turns out this is a rather advanced topic that deservessome discussion, so we recently put all of our notes and experiences intoa Wiki article that we felt was worth blogging about. To make a long story short, many users get confused about the variousGNU Compiler (gcc) options for floating point. The most commonmisconception is that ‘-mfloat-abi=softfp’ means that you are usingsoftware floatingpoint math when in fact that produces binaries thatuse hard float acceleration (as specified by the -mfp) agument butwith a function calling convention compatible …
